This attribute controls whether curves and markers are clipped at the
boundary of the graphics box specified when the Plot was created. A
value of 3 implies both markers and curves are clipped at the Plot
boundary. A value of 2 implies markers are clipped, but not curves. A
value of 1 implies curves are clipped, but not markers. A value of
zero implies neither curves nor markers are clipped. The default
value is 1. Note, this attributes controls only the clipping
performed internally within AST. The underlying graphics system may
also apply clipping. In such cases, removing clipping using this
attribute does not guarantee that no clipping will be visible in the
final plot.
The astClip function
can be used to establish generalised clipping within arbitrary
regions of the Plot.
